Abu Dhabi is the capital of the United Arab Emirates It is a very popular cruise port, both as a hub for itineraries in the Persian Gulf and as a stop on repositioning routes. One of the worlds richest cities, it has grown very rapidly over the last ten years from a small, low level fishing port to a modern metropolis of towering skyscrapers and ultra modern buildings. Some of the best tourist attractions are further out of town and of these the most important is the Sheikh Zayed Grand Mosque which is truly unmissable.
